Au fost preg\u0103tite versiuni corective pentru OpenVPN 2.5.2 \u0219i 2.4.11, un pachet pentru crearea de re\u021bele private virtuale care permite organizarea unei conexiuni criptate \u00eentre dou\u0103 ma\u0219ini client sau asigurarea func\u021bion\u0103rii unui server VPN centralizat pentru utilizarea simultan\u0103 de c\u0103tre mai mul\u021bi clien\u021bi. Codul pentru OpenVPN este distribuit sub licen\u021ba GPLv2, iar pachetele binare gata sunt formate pentru Debian, Ubuntu, CentOS, RHEL \u0219i Windows. <\/p>\n

\u00cen noile versiuni a fost remediat\u0103 o vulnerabilitate (CVE-2020-15078) care permite unui atacator de la distan\u021b\u0103 s\u0103 ocoleasc\u0103 autentificarea \u0219i restric\u021biile de acces pentru a provoca scurgeri de date cu privire la configura\u021biile VPN. Problema apare doar pe serverele configurate s\u0103 utilizeze autentificarea \u00eent\u00e2rziat\u0103 (deferred_auth). Un atacator, \u00een anumite circumstan\u021be, poate for\u021ba serverul s\u0103 returneze un mesaj PUSH_REPLY cu date despre configura\u021bii VPN<\/a> \u00cenainte de a trimite mesajul AUTH_FAILED. Combinat cu utilizarea parametrului «—auth-gen-token» sau aplicarea de c\u0103tre utilizator a unei scheme de autentificare bazat\u0103 pe tokenuri, aceast\u0103 vulnerabilitate poate duce la ob\u021binerea accesului la VPN folosind un cont inactiv. <\/p>\n

Printre modific\u0103rile care nu sunt legate de securitate se num\u0103r\u0103 extinderea informa\u021biilor despre cifrurile TLS convenite pentru utilizare de c\u0103tre client \u0219i serverul<\/a>. Au fost ad\u0103ugate informa\u021bii corecte despre suportul TLS 1.3 \u0219i certificatele EC. De asemenea, absen\u021ba unui fi\u0219ier CRL cu lista certificatelor revocate la pornirea OpenVPN este acum interpretat\u0103 ca o eroare, ce duce la oprirea sa.
